Description
Affiliated field:
The utility model belongs to a kind of sewage disposal device, particularly a kind of sequencing batch membrane bioreactor.
Background technology:
Existing sewage disposal device is generally traditional active mud and handles, and complex process need be provided with just pond, shallow lake, secondary sedimentation basins, so floor space is big, investment and operational and administrative expenses height, level of automation are lower.
Summary of the invention:
The purpose of this utility model just is to provide a kind of sequencing batch membrane bioreactor, this reactor simple in structure, floor space is little, less investment, can realize PLC control.
The technical solution of the utility model is: a kind of sequencing batch membrane bioreactor is characterized in that: be made up of equalizing tank, reaction tank, recycle pump, aeration pump, accurate filter, membrane separation unit, anti-washing unit and PLC Controlling System; Equalizing tank communicates with reaction tank by lift pump, and reaction tank is connected with recycle pump, aeration pump and membrane separation unit respectively; Recycle pump is connected with accurate filter; Accurate filter is connected with membrane separation unit; Membrane separation unit is connected with the backwash device.The PLC Controlling System is connected with equalizing tank, reaction tank, recycle pump, aeration pump, accurate filter, membrane separation unit, anti-washing unit.
Above-mentioned backwash device is made up of backwashing pump and back wash tank, and backwashing pump is connected with back wash tank.
The utility model has the advantages that: this device can carry out intermittent water inflow, intermittent drainage, reactor certain regulating power, can play the effect of the balanced water quality and the water yield to a certain extent.Adjusting, hydrolysis and acidification technique can be combined simultaneously, thereby save investment and operational and administrative expenses.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model
Embodiment:
As shown in the figure: a kind of sequencing batch membrane bioreactor is characterized in that: be made up of equalizing tank 1, reaction tank 2, recycle pump 3, aeration pump 4, accurate filter 5, membrane separation unit 6, backwashing pump 7, back wash tank 8 and PLC Controlling System; Equalizing tank communicates with reaction tank by lift pump 9, and reaction tank is connected with recycle pump, aeration pump and membrane separation unit respectively; Recycle pump is connected with accurate filter; Accurate filter is connected with membrane separation unit; Membrane separation unit is connected with backwashing pump.The PLC Controlling System is connected with equalizing tank, reaction tank, recycle pump, aeration pump, accurate filter, membrane separation unit, anti-washing unit.
The principle of work of this device is: sanitary sewage enters equalizing tank after grid is removed macrobead, enter reaction tank through lift pump.Sewage is in idle state before entering reaction tank, and leave the active sludge that precipitate in the pond this moment.Carry out the aeration operation after sewage is filled with, and this pond can be regulated sewage quality effectively.After the aeration action stops, mixed solution is remained static, carry out mud-water separation, start recycle pump then, the water of biochemistry is input to membrane separation unit, water in the generation, simultaneously a part of concentrate recirculation is in reaction tank, when membrane separation unit after operation for some time, and PLC Controlling System automatic backwash device, to clean the residual mud on the membrane separation unit, guarantee the stable of membrane flux.Stopper film tripping device operation after the water level in the reactor arrives the control water level.
